Hi jmvca:
Most likely the tuner is starting to fail. When it is first turned on, tap or slap the side of the cabinet to see if it makes any difference.

The set will have to be repaired in a shop when it goes out completely.

I have tv a cs 27205 that the image show big spots


Sounds like the picture tube is burnt out. It can happen when the television is left in direct sunlight. There is no cure for it, you can however put in a darker area and over time it may clear itself up.

How to fix TV


I have a large black square obscuring the picture. You can see the picture in 1 inch border around the black square. If I reset the input switch, the black square disappears for about one second (the picture is momentarily perfect) and the black square appears again. It is not the cable box because I wired the cable directly into the tv. The same thing happens when I try to play a DVD. Any insights????

RCA TV, model number 32V550T. No picture but sound is fine.


hiya

this sometimes is quite simple to fix as it cud be a dry joint on the circuit board where the tube motor sits.


or it cud be the tube is on its way out, which wud be cheaper to buy a new tv rather than have it fixed

No picture


Try a "hard restart"', which simply means unplugging the power cord of your TV, and replugging it after 4 hours have passed. This technique helps to reprogram the electronics of your TV.
Hope this suggestion works for you.

Sony Trinitron - Picture Disappears


Hi, IK circuit is engaging which basically means the picture tube is getting tired, the only "fix" is temporary (may get another year out of it). You have to increase the "screen control clockwise".
Remove back of set, follow large black or red wire attatched to picture tube down to the flyback transformer, mounted on flyback are two black controls, one is focus (leave it alone) the other is "screen", adjust it clockwise approx. 1/4 inch, remember that this is a high voltage circuit so use one hand in the set the other hand out of the set at all times,any questions ? e-mail me back, good luck, BMW Rider

Sounds like horizonal output transistor could be over heating. There could be other problems. But I would start there. You can find the part number on the schematic inside the set. If you change it yourself don't forget to use the included insulater. Part should cost between 15 & 20 dollars. You will need make & model # of set at electronic parts store.
Diagrahm inside set will show you location of transistor.

No picture, only sharp, squeaky noise


I'm having the same exact problem with mine! I'm looking for a solution also. I opened up the back of the TV and blew out the dust. Then I checked all connections. I put it back together and plugged it in. Now it doesn't make the high-pitched squeeking sound, but I still don't get a picture. My guess is the picture bulb is burnt out. I'm trying to find one online and am planning to fix it myself - wish me luck!
